What is Sodium 3-nitrobenzenesulphonate CAS 127-68-4？

Sodium 3-nitrobenzenesulphonate CAS 127-68-4 white crystals. Dissolve in water and ethanol. A mild oxidant that can protect the color light during fabric printing or pad dyeing steaming. It should be attached with a stop blade or coating during fabric refining and silk polishing to counteract the effect of reducing substances. It can also be used as an oxidant during dye synthesis.

Application

1 Mild oxidant

Sodium m-nitrobenzene sulfonate can protect the color when printing or pad-dyeing and steaming fabrics. When scouring and mercerizing fabrics, it is necessary to add stopper wire and coating to offset the effect of reducing substances. It can also be used as an oxidant in dye synthesis.

2 Color protection agent

Sodium m-nitrobenzene sulfonate is used as a dye resist for reducing dyes and sulphur dyes and a color protection agent for dyes, a rust remover for ships and a nickel stripping agent for electroplating. It is also an intermediate for dyes and vanillin.
